Comparison of Iterative Detection Schemes for MIMO Systems With Spreading Based on OFDM
Overview This paper considers a coded transmission over a time-invariant MIMO channel, where channel state information is present at the receiver but not at the transmitter. As basic modulation technique OFDM is applied. In addition to MC-CDM spreading techniques, the paper introduces a new class of spreading matrices that works both in antenna and frequency direction, referred to as Multi-Carrier Cyclic Antenna Frequency Spreading (MC-CAFS).
